Create the perfect water balance with automated controls

During Wageningen University’s Autonomous Greenhouse Challenge team AuTomatoes applied the principles of Plant Empowerment in their winning AI strategy. Thus, the team’s strategy was focused on the plant and it’s balances, in order to create a balanced and empowered crop. So how did they do this? This article explains all about the water balance and how team AuTomatoes kept it in balance at all times.

The water balance is the balance between the input to and output of water from the plants. Output of water is mainly caused by evaporation. Only a little portion of the total water uptake is stored in the plant and the fruits. Plants need to evaporate and thus take up water from the root zone for three reasons: the uptake of nutrients, for growth, and for cooling. In order to keep the water balance in balance, the uptake of water from the root zone must equal at least the evaporation rate. Thus, to ensure sufficient water availability, irrigation needs to be aligned with the plant’s evaporation rate.

Various algorithms were developed to support the tomato crop’s water balance in order to optimize the tomato yields. For example, some of these algorithms made use of a plant temperature sensor and pyrgeo sensor to calculate the net radiation on plant level. Based on this calculation the algorithms decided on the optimal screen position for the crop to receive the right amount of radiation to keep a steady evaporation rate.

Water holding capacity is greatly influenced by the size of the growing medium particles. Coarse particles create macropores which account for drainage and air porosity, while fine particles create micropores which retain water. A mixture of coarse and fine particles can be prejudicial for a substrate…

“Some people tend to have a myopic view that water safety is only a third world problem, however that isn’t the case. Understanding water composition is mission-critical to people and businesses around the world, so we need to start with water quality in our own backyard “. - Meena Sankaran  Predictable water insights Indoor farms…

Plants need water and fertilizer to grow. In the hi-tech glasshouse industry, growers apply both at the same time. A fertilizer injection system provides the fertilizer, and the drip irrigation system distributes the water evenly to the plants. How hard can it be? When Godfrey Dol, he is writing the…

You wouldn't expect to find a farm in an industrial park in the middle of New Jersey. Specifically, you wouldn't expect to find a farm down the road from Newark Airport, where it's 100 degrees in the shade and the scenery consists of trucks and parking lots. But I haven't come here to find a bucolic…
